I have a 2005 Jeep Cherokee Laredo. A couple months ago the interior lights started flashing. After a while the automatic locks stopped locking (They will still unlock the vehicle). Recently, the headlights started flashing. I had a diagnostic ran on it and it gave me a "Low Voltage" Message. Code 562.

Any ideas???

 

Id say go to autozone and have them test your battery, its free.

 

How many miles? What engine?

Could be the alternator.

 

Also check the grand cherokee tech section for answers as maybe more people with your model have had similar problems

 

i would say alternator or battery
